Why is Aeration Best in the Fall?

When spring has sprung, it’s easy to get carried away with gardening and home improvement projects. Flowers and trees start blooming and you start to pay attention to any flaws in your lawn once the temperatures rise. There’s plenty of work to be done to get your lawn ready for summer fun!

But think back to what your lawn looked like at the end of last summer. A summer of mowing, watering and hot sunshine leaves your lawn in need of some rejuvenation. The grass just isn’t as lush as it was in the spring, and brown patches, withered grass, and compacted soil have started to take over the yard.

We’re here to tell you that the cure is aeration - and contrary to what you may believe, aerating your yard in the fall will be FAR MORE beneficial than in the spring. Not only will fall aeration revitalize a tired lawn after a long summer, but it prepares your lawn for a harsh Colorado winter, giving it the protection it needs to stay healthy until spring comes around again!

What is Aeration?

When we help people with their lawns and ask the last time they had it aerated, we find that many homeowners don’t know what lawn aeration really is, or why it’s beneficial. 

Aeration is the process of creating thousands of tiny holes all across your lawn. Over time, your soil gets compacted from sun exposure, hard rain, and excessive use, and this makes it difficult for the roots of your grass to get access to what they need most. Aeration solves that problem, punching holes in the soil that allowing fertilizer, nutrients, and water to have easy access to the roots of your yard.

Benefits of Fall Aeration

Most grass in Colorado is cool season turf. Cool season grasses slow their growth in the fall before becoming dormant in winter, making this season the best time to aerate. Colorado’s soil stays warm until mid-November, meaning that aeration in September through November is ideal to allow nutrients, water, and oxygen to reach deep into the turf.

To help your lawn be as healthy and luscious as possible we highly recommend fall aeration. Here’s why:

Roots

Your cool season grass will start to slow its growth in the fall, but its roots will continue to grow. By helping your grass’s roots have easy access to fertilizer, nutrients, and water, you’re helping them grow deeper into the soil. The deeper the roots the stronger and more resilient the grass.

Reduces Weeds

When you aerate the soil you give the roots of your grass more breathing room. This added space encourages the roots to expand through the soil. Weeds can not grow in an area that is already full of healthy grass roots, so strong grass roots make it harder for weed seeds to take root and surprise you next spring!

Weathering Winter

In Colorado we’re used to some harsh, cold winters. Often times, lawns that are withered and exhausted in the fall don’t survive the cold temperatures, making it expensive come spring to fix all the brown patches. What’s more, once the brown patches are handled, it may take weeks for new grass to take root and grow. This means that you may need to invest in a few weeks of corrective action to nurse your backyard back to health!

Aerating in the fall will rejuvenate your lawn, making it better equipped to handle our freezing winters and setting it up for success once spring arrives!

Encourages Fresh Growth

While grass can live for a long time, fresh growth is still important! Without fresh grass, large areas can die off all of a sudden, leaving big bare patches in your yard. Aeration takes care of this problem by encouraging fresh growth of healthy grass in your yard, keeping it thick and healthy all season long.

Kiss Thatch Goodbye!

Over time, thatch will naturally build up on your soil. Thatch is a layer of organic material that develops between your grass and your soil, composed of dead and dying shoots, stems, roots, and grass clippings - and once it starts accumulating faster than natural microorganisms can break it down, it can wreak havoc on your lawn.

Aeration punches through layers of thatch, restoring your grass’ ability to breathe!
